Claims priority, application Sweden Aug, 6, 11 i? 4 Claims. Cl. ire-see) The present invention relates to so called marking machines which are used in the clothing industry for reproducing the pattern of a dress or the like on a textile fabric by transferring thereto the contours of templets placed upon the laid-out fabric. The invention is concerned with marking machines of the kind which comprise a table for the laid-out fabric, a device which is displaceable over the table top and adapted to spread out a coloring matter over the fabric and the templets while being as displaced, the templets being distributed over the surface of the fabric in spaced relation, so that the fabric will receive a coating of said coloring matter only in the areas not covered by the templets. More specifically the invention relates to such marking machines of this kind which are provided with a net adapted to be positioned over the templets during the coloring operation for retaining the templets in their correct positions on the fabric.

In machines of the above-mentioned type it is previously known to arrange the net which retains the templets on top of the fabric in a frame which is pivotally mounted at one of the longitudinal sides of the table, so that the net may be moved away by swinging said frame upwardly for permitting the {fabric and the templets to be laid out on the table. By this mounting of the net frame the table top will be accessible only from one of the longitudinal sides of the table which imposes a restriction on the usability of this structure, in that the width of the table should not be greater than to permit the person placing the templets in their assigned positions on the fabric to reach across the whole table comfortably from the accessible longitudinal side. Previously it has therefore not been possible in practice to construct machines of this kind for marking a full-width web of fabric, that is with a width of about 150 cm.

The invention which has for its object to overcome the above-mentioned drawback is mainly characterized in that the net is supported at two opposite edges by supporting members which are displaceable in guides extending along two opposite sides of the table, such that the net is movable from a position overlying the table top to a position uncovering the table top, and vice versa, the table top being movable up and down, so that when the net is in its position overlying the table top the latter may be raised so as to abut against the net. In a machine constructed in this manner both longitudinal sides of the table are accessible for placing out the templets.

According to the invention, the guides for said supporting members carrying the net are preferably arranged at the longitudinal sides of the table and are in the form of endless tracks each comprising at upper horizontal portion disposed a distance above the lowermost position of the table top and a lower horizontal portion disposed a distance \below the lowermost position of the table top.

The supporting members for the net at each side of the table are preferably connected with an endless chain extending alongside the endless guide rail, said chain passing over chain wheels arranged at the ends of the guide track and being adapted to be driven by an electric motor or the like for moving the net from a position below the table top to a position above the table top, and vice versa.

According to one embodiment of the invention the vertically movable table top is supported at two opposite "ice edges by two shafts rotatably journalled at two opposite sides of the table, the table top being connected to said shafts by means of flexible members co-operating with wheels or the like secured to said shafts, the latter being arranged to be rotated in synchronism in one direction or the other for raising or lowering the table: top by cau ing said flexible members to be wound up on said wheels or wound off therefrom, respectively.

The invention is illustrated in the accompanying drawings, wherein:

FIGURE 1 is a partly broken top elevation of a machine constructed in accordance with the invention;

FlGURE 2 is a longitudinal section taken on the line HlI in FIGURE 1, and

FlGURE 3 is a cross section to a larger scale and taken on the line IHIH in FIGURE 1 but showing the net in a different position.

In the drawings, numeral 1 designates a table, the top 2 of which is intended to serve as a support for a laid-out textile fabric 3 upon which a pattern is to be reproduced. The pattern is defined by means of templets of paper or the like and placed upon the fabric in spaced relation. The pattern is transferred to the fabric by means of a color application device 5' and displacea-ble along and above the table top, said color application device provides a colored coating evenly distributed over the whole width of the fabric, whereby the latter will be provided with a colored coating in the areas not covered by the templets. Numeral 6 designates a net which, when the coloring matter is applied by displacing the color application device from the end position shown in FIGURES 1 and 2 towards the opposite end of the table, is disposed above and lying against the templets, whereby the latter are maintained in position during the color marking. The color application device may be of any known type, for instance as described in applicants US. Patent No. 2,877,589.

The upper portion of the table It is constructed as a frame-work comprising at the long sides of the table mutually parallel upper and lower side members 7 and 8, respectively, of L-section. In the proximity of each end of the table there is rotatably joumalled a transverse shaft 9 and 13, respectively, each carrying a drum 11 and 12, respectively, and a pair of chain wheels 13 and is, respectively, disposed at opposite sides of each dru n. At each longitudinal side of the table there is arranged an endless chain 15 passing around the chain wheels 13 and 1dand carrying a number of fingers l6 evenly spaced along the'chain, the longitudinal edge portions of the net 6 extending between the long sides of the table being secured to said fingers. The opposite ends of the fingers 16 project into an endless guide channel 17 extending along the chain 15 and secured to the side members 7 and 8 of the table. On that end portion of each finger it? which is situated within the channel 5 7 there are journalled two freely rotatable rollers 18 running on one of the side walls of the channel.

To one end of the shaft 9 there is further secured a pulley 19 for a belt 2% driven by an electric motor not shown in the drawings. By rotating the shaft 9 by means of said electric motor the net will be moved by the fingers 16 connected with the chains 15 along the track formed by the guide channels 17, whereby at the ends of the table the net passes over the drums 1-1 and 12. Consequently, by rotating the shaft 9, the net may be moved from a position between the lower frame side members 8 to a position between the upper frame side members 7, in which latter position the net is situated above the table top 2.

At each longitudinal side of the table there is arranged a horizontal, rotatably journalled shaft 21 on which there are secured a number of sprockets Z2 spaced along the a shaft. Each of the sprockets is in engagement with a short chain 23 which has one end secured to the sprocket and the opposite end attached to a frame 24 secured to the under side of the table top. The table top is thus supported by the two shafts 21 by the intermediary of the chains 23 and the sprockets 22 and may be raised and lowered by rotating the shafts in such direction as will cause the chains to be wound up on the sprockets or wound oft therefrom, respectively. For rotating the two shafts there is arranged a geared motor or the like, not shown in the drawings, said motor driving, by means of a belt 25, a pulley 26 secured to one end of a transversely extending shaft 27 arranged near one end of the table, and from which the shafts supporting the table top are driven in synchronism by means of gearing 28.

The templets are placed upon and distributed over a textile fabric laid out on the table top, while the latter is in its raised position and the net is in the lower position between the lower frame side members 8, i.e. below the table top. After the templets have been placed upon the fabric the table top is lowered and the drive motor for the net is started, so that the latter is moved toits position covering the table top, whereupon the table is raised to engage the net, and coloring matter is applied by displacing the color application device along the table.

To prevent the driving mechanism for the net to be started while the table top is in its upper position, a limit switch is advantageously mounted at a suitable place of the table and adapted to be operated by the table top 2 or by the frame 24 connected therewith or by a cam or the like arranged on one of the shafts in the driving mechanism for the table top, when the table top is in its lowermost position, and adapted to permit starting of the drive motor for the net only in this position of the table top. It would be of advantage also to provide a limit switch which is operable in such a way by the top surface of a textile fabric, that the upward movement of the table top Will be interrupted, when theupper surface abuts against the net. Due to the fact that the table top may be raised and lowered relative to the plane of the net there is obtained a further advantage in that an arbitrary number of layers of fabric may be placed upon the table while the upper layer is being marked. In FiG-URE 3 a number of layers of fabric are indicated at 3 The invention is not limited to the embodiment hereinbefore described and shown in the drawings, said embodiment being chosen as an example only and being sus- 4 ceptible of various modifications with respect to its details without departing from the basic concept of the invention. It is obvious that the arrangement according to the invention may be used also for marking other materials than textile fabric, for instance work pieces of leathor, plastic, wood, sheet metal and the like.
